yup over 128 file size it starts to run into problems, but realistically how many users will need performance at those file sizes? some might, but for others...it will be interesting. however, i think file sizes that large are not that large of an indicator of the real world performance. the sequential at and under 128 do look good though, but not near what the 9260 pumps out
i think cache is really only needed for devices with write issues. this proves that you can get performance without the large caches.
